The Acute Effects Of Static Stretching Of The Gastrocnemius On Limits Of Stability In Young Adults Versus Elderly Adults, Matt Bugnet, Kirk Player

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background and Purpose: Balance is an important part of everyday life for all individuals with many body systems interacting to achieve optimal balance. Proprioceptive organs aid in this interaction, while also acting as stretch receptors. Therefore, it is possible that stretching may influence the overall balance of the individual. The purpose of this study was to investigate the acute effects of stretching on dynamic balance of healthy young and elderly adults. The two groups were used to determine if stretching may discriminately affect balance at different ages.

Subjects: Thirty healthy adults between the ages of 18 and 35 …

Agonist And Stabilizer Muscle Activity During A Push Up On Unstable Surfaces, Anthony J. Dyrek

UNLV Theses, Dissertations, Professional Papers, and Capstones

A recent trend among fitness professionals is to have clients perform resistance exercises on unstable equipment. Anecdotally, this is done with the intent that stabilizing and agonist muscles are more active while doing certain exercises on unstable surfaces. However, there are limited data as to whether or not this is the case and no studies have investigated muscle activity while doing the same exercise on surfaces that offer different levels of stability. Therefore, the purpose of this study is to measure electromyography (EMG) during push up exercise performed on unstable surfaces as well as on the ground. Surface EMG was …

The Comparison Of Hamstring/Quadriceps Strength Ratio In The Dominant Versus The Non-Dominant Leg Of Elite Female Artistic Gymnasts, Marina Moure

Human Movement Studies & Special Education Theses & Dissertations

The majority of the injuries in women's artistic gymnastics occur in the lower limbs (Marshall et al, 2007). Hamstring muscle strains are prevalent in sports that involve sprinting (Ekstrand & Quillist, 1985; Orchard, 2001; Croisier et al., 2008) with a high reinjury ratio (Orchard, 1993; Orchard, 1997). Recent studies have linked an increase of muscle injury rate in the lower limbs to strength muscle imbalance between legs and the relation between the hamstring and quadriceps strength (Croisier et al., 2002; Yamamoto, 2008; Sugiura et al, 2008). In order to determine if there is an imbalance in women's artistic gymnastics, forty-three …

Plasma Fetuin-A Concentrations In Young And Older High- And Low-Active Men, Nathan T. Jenkins, Jennifer A. Mckenzie, James M. Hagberg, Sarah Witkowski

Exercise and Sport Studies: Faculty Publications

Fetuin-A is a liver-derived factor that may play a role in insulin resistance and age-related chronic diseases (eg, type 2 diabetes mellitus and cardiovascular [CV] disease). Regular exercise improves CV risk and insulin sensitivity; however, it is unknown whether chronic exercise training is related to circulating levels of fetuin-A. Therefore, this study examined whether plasma fetuin-A levels were related to age and chronic physical activity in men. We hypothesized that chronic physical activity would be related to lower plasma fetuin-A levels in younger and older men. In healthy high-active (HI) and low-active (LO) young (HI, n = 7; LO, n …
